APPENDIX 2.2 Related Systems and Error Processing

There are following 2 types for the related systems of virtual mode.
• System consisting of a drive module and output module.
• Multiple systems used the same drive module.
The following processing occurs, when the error is detected at an output module.
• If an error is detected at least one output module, a drive module cannot start and
that system cannot be operate.
The auxiliary input axis operation for the erroneous output module also cannot
operate.
• Other systems which use the drive module which could not start by the output module
error also cannot operate.

"a", "b", "c" for system 1, a drive module "A"
cannot start and system 1 cannot operate.
The drive module "A" at system 2 cannot
also start.
for system 1, a drive module cannot also
start. Since the drive module "B" for system 3
cannot also start, the system 3 cannot also
start.
